Question

How do you solve `9-3w=2=4w`?

Answer 1

There is no definite answer to this problem as it is written. However if one equal sign were changed to a positive sign, it is possible to solve the problem.

Explanation:

`9-3w=2=4w`

The equation has two equal signs. More than likely, one of the two `=` symbols was meant to be a `+` symbol, since they are on the same key.

If we change one of the `=` signs to a `+` sign, technically it could mean `9-3w+2=4w,` or `9-3w=2+4w`.

One Possibility

`9-3w+2=4w`

Add `3w` to both sides.

`9+2=7w`

`11=7w`

Divide both sides by `7`.

`11/7=w`

Switch sides

`w=11/7`

A Second Possibility

`9-3w=2+4w`

Subtract `9` from both sides.

`-3w=2+4w-9`

`-3w=4w-7`

Subtract `4w` from both sides.

`-3w-4w=-7`

`-7w=-7`

Divide both sides by `-7`.

`w=1`
